Sierra 18-7222 - Johnson/Evinrude Carburetor Kit with Float

Sierra 18-7222 — Johnson/Evinrude Carburetor Kit with Float

Sierra 18-7222 is a complete carburetor rebuild kit, including the float, for Johnson and Evinrude outboard engines. Having the float included alongside the standard gaskets, needle, and seat means one order gets you every wear part needed for a proper rebuild, rather than tracking down a float separately. Rebuilds one carburetor. Replaces Johnson/Evinrude 392061, 398729, and 396701; Mercury 879054A1; and Mallory 9-37107.

Frequently Asked Questions

Q: How do I confirm this kit fits my Johnson or Evinrude outboard?
A: Cross-reference your carburetor's OEM part number against the list above, or send us your outboard model, year, and horsepower and we'll confirm fitment — by email, text, or live chat.

Q: I have a Mercury outboard with part number 879054A1 — is this kit correct?
A: Yes, Mercury 879054A1 cross-references to Sierra 18-7222. We'd still recommend confirming against your Mercury service manual or parts diagram, or reaching out to us, before ordering.

Q: Does this kit include the float?
A: Yes, this is a complete rebuild kit that includes the carburetor float, so you don't need to source it separately.

Q: My outboard has two carburetors — how many kits do I need?
A: One kit per carburetor. For a twin-carb engine, order two kits, and rebuild all carburetors on the engine at the same service interval.

Q: Can I rebuild a varnished carburetor with this kit, or do I need to replace the whole carb?
A: Light to moderate varnish can be cleaned with carburetor cleaner and compressed air, and this kit provides all the new soft parts to complete the rebuild. Heavy varnish blocking passages, or a cracked body or worn throttle shaft, calls for a full carburetor replacement instead.
